Julien Bayle

Julien Bayle owns his Master Degree of biology & computer sciences in 2000. After several years in pure IT System Design, he founded Design the Media early 2010 in order to provide his own courses, training & tools for art fields. As a digital artist, he designed some huge new media art installations, like the permanent exhibition of La Maison des Cinématographies de la Méditerranée (Château de la Buzine) in Marseille, France, in 2011. He also works as a new media technology consultant for some private & public entities. As an A/V live performer, he plays his cold electronic music from New York to Marseille, where he actually lives. Arduino framework is one of his first electronic hardware studies early 2005 and he designed the famous protodeck controller with some opensource framework too. As an art & technology teacher, also certified by Ableton in 2010, he teaches a lot of courses about the digital audio workstation named Ableton Live, about the real-time graphical programming framework Max6 and also about Processing and Arduino. As a minimalist digital artist, he works at the crossroads of sound, visual and data. He explores relationships between sounds and visuals through his immersive A/V installations, his live performances and his released music. His work, often described as “complex, intrigating and relevant”, tries to break classical codes to bring audience a new vision of our world through his pure digital and real-time generated stimuli. He's deeply involved in the open source community and loves to share and provide workshops and masterclasses online and on-site too. His personal website is http://julienbayle.net.

Data storage with EEPROMs

Until now, we learned and used the Arduino boards as totally electricity dependent devices. Indeed, they need current in order to execute tasks compiled in our firmware.

As we noticed, when we switch them off, every living variable and data is lost. Fortunately, the firmware isn't.

Three native pools of memory on the Arduino boards

The Arduino boards based on the ATmega168 chipset own three different pools of memory:

  • Flash memory

  • SRAM

  • EEPROM

The flash memory is also named program space. This is the place where our firmware is stored.

The SRAM stands for Static Random Access Memory and is the place where the running firmware stores, reads, and manipulates variables.

The EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is the place where we, programmers, can store things for long-term purposes. This is the place where our firmware sits, and anything in the EEPROM isn't erased should the board be switched off.

ATmega168 has:

  • 16000 bytes of Flash (2000...
